The 24/00Z forecast cycle guidance appeared to be in line with the
current Hawai'i forecast philosophy.

Short-term...
The 24/00Z GFS is a slightly faster solution (versus the ECMWF)
--- with respect to the frontal progression through the forecast
area. But both are reasonably centered on the 26/00Z-26/12z time
frame when a moderate northeast tradewind circulation becomes
re-established across the entire island chain.  and takes control
of the low-level flow pattern.

Medium range...(Sat-Tue)
All indications point to a strengthening upper-level ridge
pattern---migrating from west to east along 25N---this weekend.
For early next week, suggest blending the 24/00z ECENS/GEFS to
handle the timing and trajectory of the next mid-latitude frontal
progression. The GFS and ECMWF differ slightly with its strength,
but generally have expect some slackening of the Trades around the
2/00Z time frame (late day 7).
